ANTI-FRICTION JOURNAL=BEARING.

SPECIFICATION forming part of Letters Patent No. 391,184, dated October16, 1888.

Application filed June 12, 1888.

T0 aZZ whom it may concern.-

Be it known that I, MIoHAEL J osEPH OHARA, a citizen of the UnitedStates, residing at New Orleans, in the parish of Orleans and State ofLouisiana, have invented certain new and nsefullmprovements in a Journalfor Starting a Car; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in lubricatingjournal-boxes ofthe class in which friction-rollers are employed; and it consists in theconstrucliomnovel arrangement, and adaptation of devices, as will behereinafter more fully set forth, and particularly pointed outin theclaim appended.

In the accompanying drawings, Figure 1 is a vertical cross-sectionalview of a car-axle spindle, the same continuing through my improvedaxlc-box andlubricator. Fig.2isa horizontal sectional View of the boxremoved from the axle-spindle. Fig.3 is a plan view of the box. Fig. 4is a detail view of one of the frietion-rollers which I employ, and Fig.5 is a view of one of the bearings for the said rollers removed from thebox.

Referring by letter to the said drawings, A indicates an axle-spindle,which may be that of a streetcar axle.

13 indicates my improved axle-box, which is of a form substantially asshown, and provided in its upper side longitudinally with an oil orlubricant receptacle, A,which may be covered with a suitable plate ortop to prevent rapid evaporation and exclude dust, dirt, and the like.This box B is, furthermore, provided at opposite sides with longitudinalvertical flanges, which depend from the receptacle a sufficient distanceand are adapted to embrace the axle-spindle, as more fully shown in Fig.1 of the drawings.

Serial No. 276,891. (No model.)

C indicates bearing-blocks for friction-rollers, the form of which isbetter shown in Fig. 5 of the drawings, and there is one of these blocksemployed transversely at each end of the box beneaththelubrieant-chamber. These blocks are grooved vertically at oppositeends, as shown at d, to receive tongues or projections 6, formed atopposite points on the inner sides of the vertical flanges of the box B,so that the said blocks may be prevented from lateral displacement andyet allowed to adjust themselves with respect to the aXIespindle.

D indicates the friction-rollers, which have an upper bearingin theseatsf of the blocks 0, and these rollers have spindles, as shown atg,to enter the seatsf of the block 0. It will be observed that theserollers extend the entire length of the box beneath the lubricant-reeeptacle, and that the floor of the said receptacle is provided with smallapertures h, so that the lubricating material may be fed upon thefriction-rollers and from them discharged on the spindle ofthe axle. Itwill be observed that these rollers have a bearing upon the axlespindles.

Having described my invent ion, what I claim is The combination, withthe axle-box having the upper lubricantreceptacle provided with aperforated bottom and the depending flanges adapted to embrace anaxle-spindle and provided with the tongues, as shown, of thebearingblocks grooved at opposite ends to receive the tongues on theflanges of the box, and the frictiourollers arranged above theaxle-spindle and having an upper bearing against the said blocks.

In testimony whereof I affix my signature in presence of two witnesses.

MICHAEL JOSEPH OHARA.
